“Inside the tank, your brain is free to downshift and address
interpersonal projects: immune health, unification of the brain's hemispheres,
stress reduction, healing. For days afterward I feel the residual effects.
My shoulders are looser, I feel less frustrated, my outlook is more
positive. I am not a grinning fool, but my tolerance level is notches
higher than that of most city dwellers. And in this life, that's no
small thing."
